# Unset 'GUILE_LOAD_COMPILED_PATH' altogether while compiling.  Otherwise, if
# $GUILE_LOAD_COMPILED_PATH contains $(pkgmoduledir), we may find .go files in
# there that are newer than the local .scm files (for instance because the
# user ran 'make install' recently).  When that happens, we end up loading
# those previously-installed .go files, which may be stale, thereby breaking
# the whole thing.  Set GUILE_AUTO_COMPILE to 0 to avoid auto-compiling guild.
